DEVICE FOR FASTENING HORSESHOES.

SPECIFICATION forming part of Letters Patent No. 255,765, dated April 4,1882. i Application filed July 23, 188i. (Xo model To all whom t mayconcern:

Beit known that l, GEORGE BRYDEN, a citizenof the United States,residing at Hartford, in the State of Connecticut, have invented anewand useful Iinprovementin Fastenings for Horseshoes, ot' which thefollowing is a specitication.

This invention consists in certain novel substitutes for ordinaryhorseshoe-nails, Src., as means for attaching or fastening horseshoes'of any description to the hoofs ot' horses and mules.

The evils incident to nailingshoes to horses7 hoof's have long beenrecognized, and many devices and methods have been proposed as means forremedying and avoiding these evils; but horseshoe-nails driven throughthe shoe into the hoof and clinched at the outer surface of the latterare still almost exclusively used in practice, and this is owing,presumably, to the superior simplicity, cheapneSS, lightness, andneatness ot' horseshoenails as compared with other knownhorseshoe-fastenings, and more particularly' the freedom ot'properly-nailed hoofs to expand naturally to a considerablc extent, andthe adaptation ot' the nails for substantially indiscriminate use inattaching horseshoes ot' all the various patterns, and theiradaptationto bedrawn perfectly tight in applying the shoes, and to bereadily tightened when loosened by wear, with the simplicity of theadaptation of' the shoes to receive nails.

The object of the present invention is to furnish horseshoe-fasteningspossessing, iu large degree at least, the said advantages of ordinaryhorseshoe-nails, without their disadvantages or evils aforesaid.

Figures l and 2 ofthe accompanying drawings are perspective viewsrespectively of one ot' my primary fastenings or nails and one ot' mysecondary fastenings or clips. Figs. 3 and 4 are respectively a sideview and a bottom View of a horses foot shod according to thisinvention, the l'astenings at one of the nailholes being omitted in Fig.8 and the edge of the shoe cnt through said hole. Figs. 5 to 8,inclusive, are a series of vertical sections in one and the same plane,illustrating the shoeing operation 5 and Figs. 9 to 11,inclusive, are

small views of speci-.i1 tools used in applying the fastenings.

Likeletters of reference indicate corresponding parts in the severalfigures. 4

The said primary fastenings or nails are represented by A, and the saidsecondary fastenings or clips by B.

C represents a horses hoof, trative horseshoe.

The fastenings A B areintended to be made ot bar-steel or nail-rod iron,of suitable sizes, by rolling the same so as to raise suitable lugsthereon to supply metal for the heads of the fastenings, then swaging itin dies, so as to swage the fastenings in sets ot` four, more or less,at each heat, and finally trimming and separating the fastenings eitherhot or cold; but I do not limit myseifto thislnodeot' manufacture, asthe t'astenings can be readily made by other known processes by skilledblacksiniths and iron and steel 'orgers. Each of the nails Aisconstructed with a long fiat body substantially rectangular incross-section, and with a cylindrical head, h, projecting at an anglcot' Vabout eighty degrees at its upper end. The opposite extremity maybe blunt, as the nail is not driven. At an intermediate point the frontand back ofthe body of the nail are roughened, (in the roll or dies, orby any preferred means,) as shown at r. Each of the clips B isconstructed'with aninclined semicircular clip-head, c, analogous inappearance to an ordinary horseshoe clip, and with a body or and l) anillusshank substantially square or rectangular in cross-section, butpointed at its lower end, the face and back of the body being ronghened;as shown at r2. The fastenings are intended to be made of four sizes,suitable respectively for attaching the various sizes of horseshoes incommon use.

The hoot' C is prepared to receive the fasteniogs A B by means of aboring-tool, Fig. 9, and a rasp, Fig. 10, after having had the lshoe Dfitted thereto in the ordinary way. Figs.3 and 5 illustrate thisopera-tion. By said boring-tool, Fig. 9, a round hole, h', of propersize, is'ormed within the horny outer wall of the hoof, aboveeachlnail-hole a,by a cutting operation', a shoulder or stop on the bitserving to limit the penetration ot' the latter, so as to 1 ing device,as hereinafter set forth.

preclude boring too close to the sensitive inner part of the hoof.

Fig. 9 represents a boring-tool having a revolvingbit-head, b,with fourshouldered points adapted for use successively to bore holes to tit theheads of the several sizes of nails. By said rasp, Fig. 10, a suitablenotch or niek, n', is cut inthe edge of the hoof in line with the holeh', to receive the body of the nail and also that ot' the clip, so thatthe back of the cliphead e may tit snugly against the edge of the hoof,like that of an ordinary clip, adapting the latter to perform all thefunctions of an ordinary clip, while it serves to conceal said nick andco-op rates with the nail as a fasten- The particular rasp shown in Fig.l() has a, cruciform steel, s, the respective ribs of which are adaptedto cut nicks ot' the several sizes required for the four sizes ot'lastenings.

The horseshoe I) is simply provided with the required number ofnail-holes n, preferably tive, including one at the toe. In formingthese, however, I pret'er that the shoe he punched hot. so as to formthe common bulge :c at each nail-hole, as shown in dotted lines in Fig.4. A shoe having an endless vcalk is shown; but my invention isnotcontined to this variety of horseshoes, being adapted and designedfor use in attaching any kind of horseshoe that can be attached byordinary horseshoe-nails.

The method of uniting the parts is illustrated by Figs. 5, 6, 7, and 8.The hoof is held in the position most convenient to the shoer, and thetitted shoe is placed loosely thereon, as shown in dotted lines in Fig.5. The nails Aare then passed loosely through the nicksn and nail-holesn, and their heads h are snccessively driven into the hoof-holes h',which they yfit tightly, except as to depth, as shown in Fig. 6. The endof each nail protruding through the shoe is next grasped by means ofpinchers, Fig. 1I, and drawn upon and bent, as illustrated by dottedlilies in Fig. 6, preparatory to the insertion of the point of a clip,B, outside of the nail, as illustrated by Fig. 7. The clip is drivenhome while the shoe is supported by the jaws j ofthe pinchers, and thebodies of the nail and clip together tightly ll they nail-hole n, andbein g rou ghened, as aforesaid, become securely locked therein, as afile is locked against Withdrawal in a spiked cannon, and the securityof the fastenings is further increased by hammering down the aforesaidbulges x. The two protruding extremities at each nail-hole are now cutoff by means of the ordinary cutting-nippers, as illustrated by. dottedline in Fig. 7, 'and if there be anailcrease, asin the example, the endsare preferably so cut therein as to remain outof contact with the groundas long as possible, as illustra-ted by Fig. 8.

The parallel, or substantially parallel, sides of the nails A adapt themto be readily tightened by means of the hammer, like ordinaryhorseshoe-nails, should the shoe become loose.

In an inferior modification of my invention the nails A, adapted totightly fdl the nailholes, may be used Without the clips and in thiscaseclips need not necessarily be raised ou the shoes to supplementthenails; butthe described combination of partsis preferred. I

also propose, as an int'erior modification, making both sets offastenings A B of soft iron and annealing them, so that their lower endsmay be clinched Within the nail-crease, and in thiscaserougheningtheshanksmaybeomitted.

I do not claim herein the described method of making myhorseshoe-fastenings, nor the described special tools used in applyingthem; nor do I limit myself to the use ot' either, as Well-knownsubstitutes can be used; but I reserve the right to claim the same orany features thereof which may be patentable in a future specificationor specifications. y

What I now claim as new, and desire to protect under this specification,is-

l. Thewithin-described horseshoe-fastening A, constructed willi a longlat body substantially rectangular in cross-section, and with acylindrical head projecting at an angle at its upper end, substantiallyns shown, as a new article of manufacture.

2.- The combination, substantially as herein described, of a primaryfastening, A, having a head at its upper end to lit a hole in the shellof the hoof, and a body or tang to occupy a nail-hole in a horseshoe,and a secondary fastening, B, having a clip-head at its upper end, and apointed body or tang, adapted to be driven tightly into said nail-holeoutside of said primary fastening, the bodies or tangs of bothfastenings being roughened to adapt them to interlock with each otherand with the shoe, as set forth.

3. The Within-described method offastening shoes to the hoofs of horsesand mules, consisting in providing the shoes with a sufficient number ofnail-holes and cutting nicks in the edges of the hoot's to receive thefastenings, inserting primary fastenings loosely into said nicks andnail-holes, and driving their heads into said holes in the hoofs, thendrawing said primary fastenings tight and driving secondary fasteningsinto said nail-holes outside of said primary fastenings, and cutting offthe extremities which protrude through the shoes, the lower end of eachfastening heilig secured within or beneath the shoe, substantially asherein specified, for the purposes set forth.
